Hybrid tomato variety H1766

ABSTRACT

Hybrid tomato variety ‘H1766’ is described. The tomato variety is a ground-culture hybrid tomato variety suitable for machine harvest, and is adaptable to the climactic conditions of regions such as Eastern USA, Portugal, Spain, and Italy.

FIELD

This invention relates to the field of plant breeding. In particular, this invention relates to a new variety of tomato, Solanum lycopersicum variety denominated ‘H1766’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that give an advantage to the grower, processor, consumer, or other members of the supply chain. The improvement may be in the form of field performance, disease resistance, factory performance, or a fruit quality characteristic. For a tomato variety to be suitable to be grown for processing, the variety must have a concentrated fruit setting and maturity, firm fruit, and sufficient rot tolerance to allow early fruit to remain rot-free while later fruit continues to develop and ripen.

Most commercial processing tomato varieties are hybrids resulting from a cross pollination of two true-breeding, inbred parents. Through the use of true-breeding lines, a hybrid is produced that often displays characteristics of each parent, and often demonstrates characteristics that are superior to either parent alone, or that allow a hybrid to mask inadequacies of the individual parents.

Processing tomato varieties combining resistance to verticillium wilt race 1 (Verticillium dahlia), fusarium wilt race 1 and 2 (Fusarium oxysporum pv lycopersici), root knot nematode (Meloidogyne incognita) and tomato spotted wilt virus (TSWV) are highly desirable in most climates around the world. Moreover, in humid regions such as Eastern North America, there is considerable disease pressure from bacterial diseases such as bacterial canker (Clavibacter michiganenesis michaganensis) and bacterial spot caused by various Xanthomonas species. Thus, varieties with resistance are in high demand by both growers and processors to ensure a productive crop cycle. Additionally, in recent years the industry has seen an increase in the presence of Late blight (Phytopthora infestans) which can have a devastating impact on the tomato crop.

An additional important contribution that tomatoes provide to the human diet is the antioxidant lycopene. Specifically, processed tomato products are the primary source of tomato intake in the US diet. Higher levels of lycopene are beneficial both from a nutritional standpoint and from a consumer perception and quality standpoint. Tomato varieties having higher levels of lycopene result in products with a deeper red color that can be considered an indicator of higher product quality. Thus, a tomato variety with a higher level of lycopene, and improved color in general can be valuable from both a nutritional standpoint and a quality standpoint. However, to be commercially viable, the tomato variety must perform acceptably in the field and factory as required by any other processing tomato variety.

Processing tomato quality parameters differ from those of fruit used in the fresh market. The processing characteristics are typically determined using a sample of hot-break tomato pulp or juice produced in a consistent manner to those familiar with the art. For example, a fixed mass of tomatoes may be cooked in a microwave oven for several minutes to halt any enzymatic breakdown of the sample, lost water is replaced, and the sample is pulped to remove skins and seed to produce a uniform juice sample. The juice sample can be analyzed for various quality parameters important to processing tomato including but not limited to gross viscosity measures such as juice Bostwick, soluble solids measures using a refractometer (° Brix), measures of acidity and pH, and measures of color (e.g. a Hunter a/b score). The value of these traits depends on the product that is being commercially produced by the processing factory. In some instances, a factory will put a higher value on a thick viscosity variety, whereas in other instances, a thin viscosity will make a superior product and is preferred.

SUMMARY

In order to meet these needs, the present invention provides the improved tomato variety ‘H1766’; a variety that produces exceptional yields of uniform fruit and demonstrates an adaptability to humid growing conditions around the world. The variety ‘H1766’ has resistance to verticillium wilt race 1, fusarium wilt races 1 and 2, root knot nematode, tomato spotted wilt virus (TSWV). In addition ‘H1766’ also possesses resistance to bacterial spot, bacterial canker, late blight and intermediate resistance to early blight. The fruit of ‘H1766’ have strong internal color and an average fruit weight of 68 grams. ‘H1766’ presents an advantage over industry standard varieties such as H3402 in that it carries higher levels of resistance to bacterial spot, bacterial canker, early blight and late blight. Tolerance to fruit rot in ‘H1766’ is very good, allowing for once-over machine harvesting applications requiring extended field holding.

DETAILED DESCRIPTION

Described herein is the new and distinct tomato variety named ‘H1766’ that was developed to provide a ground-culture hybrid tomato variety (i.e., not grown on stakes) that is suitable for machine harvest, and are adaptable to the climactic conditions of regions such as the Eastern USA, Portugal, Spain, and Italy.

Tomato plants of ‘H1766’ are resistant to verticillium wilt race 1, fusarium wilt races 1 and 2, root knot nematode, tomato spotted wilt virus, bacterial spot, bacterial canker, and late blight, with intermediate resistance to early blight. Plants are light green in color with a sprawling habit as compared to tomato varieties of the same market class. Fruit of ‘H1766’ are firm, very smooth, and medium in size (68 gram). Both internal and external color are strong. Fruit are also considered to have an extended field storage which delays the onset of fruit rots after reaching red ripe maturity.

Stability of Variety ‘H1766’

The variety is uniform and stable within commercially acceptable limits. As is true with other tomato varieties, a small percentage of variants can occur within commercially acceptable limits for almost any characteristic during the course of repeated multiplication. However, no variants were observed during the two years in which the variety was observed to be uniform and stable.

Comparison of ‘H1766’ to Closest Varieties

Data in Tables 1, 2, 3, and 4 are based primarily upon trials conducted in Collegeville, Calif. from two replications, non-staked, in a research plot environment. Comparisons among varieties for processing traits (Table 2) were done over two years of side-by side testing throughout California. Disease resistance and adaptability assessments are based upon numerous observations collected throughout California and in regions/climates with specific disease pressure for ripe fruit rots, bacterial spot, bacterial canker, early blight, and late blight, including Ontario, Canada.

Several characteristics can distinguish ‘H1766’ from the similar commercial variety ‘H3402’. The fruit size of ‘H1766’ is significantly larger and wider than ‘H3402’; ‘H1766’ is approximately 11 grams heavier than ‘H3402’. Furthermore, ‘H1766’ shows a wider adaptation to humid climates and has resistance to late blight.

Further Embodiments

Additional methods include, without limitation, chasing selfs. Chasing selfs involves identifying inbred plants among tomato plants that have been grown from hybrid tomato seed. Once the seed is planted, the inbred plants may be identified and selected due to their decreased vigor relative to the hybrid plants that grow from the hybrid seed. By locating the inbred plants, isolating them from the rest of the plants, and self-pollinating them (i.e., “chasing selfs”), a breeder can obtain an inbred line that is identical to an inbred parent used to produce the hybrid. Accordingly, another aspect of the disclosure relates a method for producing an inbred tomato variety by: planting seed of the tomato variety ‘H1766’; growing plants from the seed; identifying one or more inbred tomato plants; controlling pollination in a manner which preserves homozygosity of the one or more inbred plants; and harvesting resultant seed from the one or more inbred plants. The step of identifying the one or more inbred tomato plants may further include identifying plants with decreased vigor, i.e., plants that appear less robust than plants of the tomato variety ‘H1766’. Tomato plants capable of expressing substantially all of the physiological and morphological characteristics of the parental inbred lines of tomato variety ‘H1766’ include tomato plants obtained by chasing selfs from seed of tomato variety ‘H1766’.

One of ordinary skill in the art will recognize that once a breeder has obtained inbred tomato plants by chasing selfs from seed of tomato variety ‘H1766’, the breeder can then produce new inbred plants such as by sib-pollinating, or by crossing one of the identified inbred tomato plant with a plant of the tomato variety ‘H1766’.

The disclosure further includes introducing one or more desired traits into the tomato variety ‘H1766’. For example, the desired trait may include male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes. The desired trait may be a genetic locus that is a dominant or recessive allele. The genetic locus may be a naturally occurring tomato gene introduced into the genome of a parent of the variety by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques. For a genetic locus introduced through transformation, the genetic locus may comprise one or more transgenes integrated at a single chromosomal location. Accordingly, the disclosure provides tomato plants or parts thereof that have been transformed with one or more transgenes (i.e., a genetic locus comprising a sequence introduced into the genome of a tomato plant by transformation) to provide a desired trait. In one aspect, the one or more transgenes are operably linked to at least one regulatory element.

The gene(s) may be introduced to tomato variety ‘H1766’ through a variety of well-known techniques, including for example, molecular biological, other genetic engineering, or plant breeding techniques, such as recurrent selection, backcrossing, pedigree breeding, molecular marker (Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), and Simple Sequence Repeats (SSRs) (also referred to as Microsatellites)), enhanced selection, genetic marker enhanced selection, and transformation. Accordingly, tomato seed, plants, and parts thereof produced by such genetic engineering or plant breed techniques are also part of the present disclosure.

Also provided herein are single locus converted plants and seeds developed by backcrossing wherein essentially all of the morphological and physiological characteristics of an inbred are recovered in addition to the characteristics conferred by the single locus transferred into the inbred via the backcrossing technique. A single locus may comprise one gene, or in the case of transgenic plants, one or more transgenes integrated into the host genome at a single site (locus). One or more locus conversion traits may be introduced into a single tomato variety.
